Description
水を電気分解するときに両極から主として発生するラジカルとしては、ヒドロキシルラジカル(OH・)、ヒドロパーオキシラジカル(HOO・)、スーパーオキシドラジカル(O2 −)、過酸化水素水(H2O2)があるが、数秒から数億分の1秒といった短時間で存在する不安定な物質であるが、イオン交換により細菌を瞬時に殺菌、消毒する機能に優れているという特徴がある。
水に直流電源を通電させると、電位差(ORP)が発生する。このとき、陽極(+)から発生する+電位差が1100mV以上であれば、大腸菌及び一般細菌が細胞膜を破壊して瞬時に細菌などの微生物を殺菌することになる。
海水を電気分解すれば、水中の塩分(NaCl)が残留塩素(OCl−、HClO)の形態に一部切り換わる。次亜塩もラジカルの一種であるが、他のラジカルとは異なり、持続力を有し、生物を殺菌することになる。海水中電気分解時に生成される残留塩素の生成濃度は電極のコーティング材質、滞留時間及び投入電力量と相関関係を有するが、高い残留塩素濃度を海に放流する場合、他の生物破壊の原因となるため、できる限り低い濃度に維持する必要性がある。このため、できる限り次塩発生量の少ない電極を用いて短い接触時間と低い電流量にて消毒することが本発明の要旨である。
